RAILROAD-SLEEPER.

SPECIFICATION forming part of Letters Patent No. 659,749, dated October16, 1900. I

Application tiled July 28, 1900.

To all whom it may concern.-

Be it known that I, HEINRICH JASSOY, professor in the Royal TechnicalInstitute of Stuttgart, a subject of the King of Prussia, Emperor ofGermany, residing at 51 Kronenstrasse, in the city of Stuttgart, in theKingdom of l/Viirtemberg, in the German Empire, have invented certainnew and useful Improvements in Railroad-Sleepers, of which the followingis a specification.

This invention comprises sleepers adapted for use with any kind ofrailroads, electric roads, tram-car roads, and the like; and it isespecially distinguished by being composed of several sections boltedtogether in any suitable manner. Each of these several sections isprovided with projections and grooves fitting into corresponding groovesand projections of the next succeeding section and is further securelyconnected by a transverse rail or bar extending over the whole length ofthe sleeper and serving for the attachment of the rails unto the same.The sectional sleepers as employed heretofore are objectionable by theirallowing of alateral displacement of the several sections, the meetingsurfaces of which were smooth, so that the weight was not evenlydistributed upon the road-bed, and the distance of the rails was changedif part of the sectional sleeper was destroyed or injured. All theseinconveniences are avoided in my invention, as pointed out in the claim.

The accompanying drawings show by way of example a preferred form ofsleeper embodying my invention.

Figure 1 is a longitudinal section, and Fig. 1 a vertical section on theline A B of Fig. 1. Fig. 2 is a top view of the sectional sleeper. Figs.3, 4-, and 5 are side and plan views of the sectional pieces and of theend piece. Fig. 6 illustrates the manner of bolting together the severalsections.

The sleeper is made up of the sections a and I), made from any naturalor artificial material or composition. 0 represents grooves on thesections preferably dovetailed and registering with correspondingprojections 01 of the next section. A bolt 6 serves to secure theseveral sections together. Some of the sections (four are shown in thedrawings) are Serial No. 25,209. (No models placed together with theirgrooved sides, so as to form holes forthe reception of fiatlocking-platesfof wedge-shaped iron secti0n,and to whose upperextremities is secured the plate or rail 9 on top of the sleeper andserving for the attachment of the rails. h represents the sectionalpieces at the extremities of the sleeper, to which are secured thefish-plates 1', having openings l for the reception of the ends of theplate or rail 9. The several sections of the sleeper are securedtogether by the bolt 6. Openings are provided in the top plate or rail gfor the entrance of the locking plate or bolt f. The bolts for attachingthe rails are passed through other openings 7c of the top plate. Beforeuniting them together the contacting. surfaces of the several sectionsare preferably coated with tar, bitumen, or the like and may be soarranged as to prevent longitudinal displacement and at the same time toallow access to the bottom of the sleeper.

By the attachment of a top plate or rail extending over the whole lengthof the sleeper it is possible to keep the rails at exactly the samedistance independent of injuries to any of the sections. By theengagement of the lateral recesses and projections or tongues theseveral sections are securely united with each other, and the weight isevenly distributed throughout and upon the road-bed.

Sleepers as constructed according to my invention are especially ofadvantage for switches where the distance of the rails and theirattachments to the sleepers under both tracks are varying. The raildistance and the attachment may be adjusted with accuracy independentupon the configuration and arrangement of the sections of the sleeper bychanging the position of the openings of the top plate or rail g. In theconstruction of sleepers as heretofore practiced switching could neverbe effected With absolute security in view of the distance of the railsbeing dependent on the sections and joints of the sleepers and rails.Destruction or injury of one of the sections will not interfere with thetrue distance of the rails, which will still be maintained by the topplate or rail, while in the sectional sleepers as used heretofore injuryto one oftheseciionsresulted in a changer plates or bolts fftherebypreventing change of distance and very often was thecause of of: raildis-tance and causing: an even distria derailment.

What I claim, and desire to secure by Let- 5 ters Patent of the UnitedStates, is-

In a sectional sleeper for railroads of any kind sectional pieces, a,I), having tongues or projections (Z, and corresponding recesses c,

and a bolt 6, for effecting their union incom- L I0 bination with a topplaie or rail g, secured to the top of the sectional sleeper by lockingbution of Weight upon the road-bed, substantially as described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing, witnesses.
